I know it's a big sucker to drop on and off, but if i can keep that pot at a lovely -190 (which should be no problem as long as i keep it full, and i can drip it right from the dewar into the pot) and pull it off for booting, it would make taking the torch to my very expensive pot less needed, even though i know it won't damage the alum or copper, just wastes ln2.
Actually the continual cycle of heat up and cool down does something to copper which makes it more responsive to ln2 over time. I've seen it for sure with my F1's. My first pot which had serious usage gradually became more responsive. When I switched to a brand new F1 I could totally see the difference. Now the new F1 is starting to get responsive after the abuse

K|ngp|n has talked about this wierd effect a few times now.
